Bureau Veritas approves EODev’s electro-hydrogen energy solutions for the maritime industry

Bureau Veritas (BV), a world leader in testing, inspection and certification, recently approved the second generation of the REXH2® developed by Energy Observer Developments (EODev), a turnkey power generator for the supply low-carbon electricity on board ships. The PEM hydrogen fuel cell at its heart makes it possible to meet energy needs ranging from 70 kW to around one megawatt when several REXH2® are installed in parallel.

The Approval in Principle (AIP) obtained by EODev for its REXH2® fuel cell design follows a thorough review of the design against the latest classification rules and regulations, assessing its compliance with IGF code-specific safety regulations for vessels using low flash point gases and fuels. It also follows the recently published BV NR 547, applicable to the use of fuel cells on board ships.

Working closely at all stages of development of the final product, Bureau Veritas and EODev produced the AIP in record time to enable the start of series production of the long-awaited marine generator set. The procedure for obtaining type approval on the final version of the new REXH2® has already started and should be completed by the end of 2022.

This achievement was also made possible thanks to the collaboration initiated between EODev and Bureau Veritas which resulted in the validation of the first generation of EODev’s REXH2® unit in spring 2021, which was extensively tested on board Energy Observer and the Hynova Yachts The New Era demonstrator.

Among the key developments between the two generations of REXH2® are the integration of the cooling and power management system and a comprehensive security system, allowing more flexibility for shipyards and naval architects to consider the use of the REXH2® in existing ships and fewer constraints for its integration into new projects.

The missions of EODev and Bureau Veritas are to ensure the safe implementation of hydrogen technologies and to promote the use of hydrogen as an energy source to support the decarbonization of the shipping industry. . BV and EODev will therefore continue to cooperate on the following activities:

  • Perform a preliminary assessment of new hydrogen marine energy solutions developed by EODev
  • Sharing technical expertise on hydrogen technologies to enable the acceleration of the use of hydrogen on board ships
  • Leverage class rules and relevant regulatory frameworks

Jérémie Lagarrigue, CEO of EODev, underlined: “Energy Observer was the first to install a hydrogen fuel cell on board an ocean-going vessel in 2017. EODev was then the first company to integrate a more powerful version of its original Range Extender into the Energy Observer catamaran. , thanks to a long-standing collaboration with. -permanent Toyota hydrogen expert, in 2019. Then came a fully certified pleasure day-boat in 2021; and now, in 2022, we are reaching a new milestone with the launch of our large-scale mass production of the latest plug & play compact REXH2®, which uses Toyota’s latest fuel cell technology. From the beginning we have worked with Bureau Veritas, and from the beginning they have not only been a great supporter of our commitments, but also a great partner in helping to make everything right to accelerate the transition to clean energy with the best and the safest. solution.”

Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas Marine & Offshore, commented: “As a classification society, Bureau Veritas Marine & Offshore works with players in the maritime industry, from offshore operators to shipowners and port authorities. BV’s ambition is to enable our customers to tackle the energy transition. We use our expertise to help advance innovation, safety and performance and to enable future-oriented solutions. As we help our customers comply with environmental regulations, implement green solutions on board, measure decarbonization progress, and more, the collaboration with EODev is another testament to our ambition and commitment. we are particularly proud.
